IMPROVEMENT IN CORN-PLANTERS.

Th Schedule referred to in these Letters Patent and making part of the saine.

To all whom it muy concern Be it 4known that l, S. Y; O'RR, of Morning Sun, in the county of Louisa, and State of Iowa, have invented anew and useful Improvement in Corn-Planters; and

I do hereby declare that the following is a full, clear,A

and exactdescription thereof, which willA enable others skilled in the art to make and use the same, reference.

different position.

Similar letters of reference indicate corresponding parts. v l Y rlhis invention relates to a new and improved cornplanter, of that class which is designed for planting in check-rows; and f It consists in a novel construction and arrangement of the same, as hereinafter fully shown and described, whereby the desired work may be performed in an expeditious manner.. 1nV the accompanying sheet of drawings- A represents the frame of the machine, which may be constructed in any proper manner, having a draughtpole, B, secured to its ti'ont end, and mounted on two wheels, (l G', which are tted loosely on their axle D, the latter being allowed to turn freely in bearings a in the frame, and the wheels U C allowed to turn on the bearings. This will be fully understood by referring to tig. 1. Y

On the shaft or axle D there are secured t-wo cams, E 1S', which are of Sfform, (see tig. 2,),and are placed on the-axle D in reversed position.

F is a lever, the front end of which is secured on a shaft, G, havingvits beal'ingsrin uprights b 1 1, on'the front part of the trame A, said shaft having a'crankarm, 11,111; each end ot' it, the lower ends of which are 4engaged with seedslides l I, titt-ed inthe bottoms of the the lever after the prominent portions of the cam,

leave it, this latter Vmovement being rendered effectual by a weight, K, placed on the lever, and in such a manner thatit may* be adjusted longitudinally", to add, in .a greater or less degree, to the eiiicieneynt' the droping movement ofthe lever, as may be required.

` The lever F is provided at each side, near its-rear end, with a short arm e.

The cams E E', act against these arms, one cam only acting at once, fthe level' F being shifted laterally, so that either cam may be made to act upon it as required.

'lhe wheel C has a concentric toothed rim, L,at tached to its inner side, and around a circular con- .centric opening, d, in the wheel.

M is a ring, which is attached to a lever, N.th

front end of the latter being secured to 'the ii'ame by v.

a fulcrum-pn, at its front end, the rear part ot' said lever being titted on a guide-plate, f, to which it may he secured at different points by a piu, g.

The ring M has a pinion, h, in it, which pinion,

Vwhen the lever N is adjusted to the right, is thrown in gear with the toothed rim L of wheel. C, andalsowith a wheel, O, on the axle D.

- This wheel O is not `firmly secured to the axle-D,

but is fitted' loosely thereon, and is'clamped between two disks P l), which disks are secured to the axle I),a rubber or elasticwasher, Q, being interposed between the wheel and each of the disks, as shown iu tig. 3.

By this arrangement it will be seen that the wheel l O may slip on the axle ift-he latter resist in a. certain degree the motion imparted to O.

AX is a latch, secured near the axle in the circular concentric opening (l, in the wheel C, which latch is pressed forward by a spring, ad, (see iigs. 3 and 5,) and engages with the toot-hed rim 'Land the wheet O, when the lever N is adjusted to the left, thus im-` 'parting to the axle D, through the medium of the wheel O, motion in the same direction as the wheel C. \Vhen thc lever N is adjusted to the right, the ring M presses back the latch AX, disengaging it from the toothed rim L and wheel O, and allowing the pinion` h to engage in its stead, thus imparting a reverse motion to the axle D, while the latch AX, which is secured to the wheel C, is carried 'around on the edge of the ring M.

On each end of 'the axle D there is keyed a reel, R,

having a tine wire, or cord, S, wound upon them.

. .l is a rod, having an anchor, V, attached to one end ot' it, and on the opposite end there is made a small hook, '42, to catch into an eye, j, attached to the ends ofthe wires S.

BX is a'small eye, through which the wire must be placed, when being rewound upon the reels, in order to guide it properly upoirgtlle reel.

It also serves to the ground in a straight line or furrow, and as the machine is drawn over tbe tield from said anchor, tho wire S, which is attached to it, will unwind from its reel with a fixed tension, 'and turn theaxle D.

After the machine is turned at the opposite side or lend of the field, it is properly adjusted for a return, in

the following manner, viz: l

The lever N is moved to the right, so as to throw the pinion hof ring M in gear with the concentric toothed rim -L andthe wheel 0; the axle D will then he turned in a reverse direction, and the wire S, which was previously unwound, wound upon its reel, and kept in the same tension in which it was uuwound, owing to the axle D having a `tendency to b e turned quicker than the wheel C rotates, the wheel O slippiugalittle on its axle. This result is due to the difference in the dimensions ofthe gearings L h O.

\Vhen the machine is being drawn from place to place, the wires me retained on their reels by the staples c,`shown in fig. l. A e

These staples are also used to keep the wire or cord from uncoiling from the reel at the side or end of the field opposite the anchor or guide-furrow. The staples are placed over the wire or cord, and on the return allow the wire o1' cord to wind on the re'el over the staples.

By this arrangement, corn may be4 planted evenly in check-rows, and very expeditiously.

Thel object of this invention is to secure, by use of a smooth wire or cord, wound around reels, a move- `ment that is independent of the ground-wheels, and

which depends ou actual space, viz, the semi-circum- `ference of the reels, for the spaces between the checks or rows.

Iwould remark that a guide-furrow may be used at one side of the field, or through the centre of it. In this latter case, the wires S ofthe two reels would be used alternately. v

Having thus described my invention,

l claim Patent- 1. The' use or employment of a smooth wire, or cord, S, wound upon the reels R, in combinationavith the friction-disks P P, with rubber or elastic washers Q' Q, and nut 1 with the cams E E', or ,their mechanical equivalent, for the purpose ot'operating` the seeddistributing mechanism, as the machine is drawn along, when constructed substantiall y as and for the purpose set forth. f

2. The rod T, provided with the anchor V, and hook Ii, in connect-ion with the eyes j, attached to the wires S, for the purpose of connecting the wires to the anchor V and rod T, when so constructed, that in combination with the small eye BX, on the front end ot' the machine, the wire will be automatically unhooked from rod T, substantiallyY as and for the purpose set forth.

3. The combination of the wires S, ,reels R, on axle Y D, cams E E', lever F, and seed-dropping mechanism, all` arranged to operate substantially as and for the purpose set forth.

.4. The toothed rim L, latch AX, spring ax, pinion h, in the ring M, attached to the lever N, and the 'wheel O, between i'liction-disks P P, on the axle D,

as new,`and desire to secure by Letters n
